WRITING-BOOK COVER.

SPECIFICATION forming part of Letters Patent No. 606,180, dated June 28,1898.

Application filed September 30,1397. Serial No. 653,538. (No model.)

To aZZ whom it may concern;

Be it known that I, CLARENCE J. AINS- WORTH, of est Gardner, in thecounty of Worcester and State of Massachusetts, have invented certainnew and useful Improvements in Writing-Book Covers; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, forming apart of this specification, and in which Figure 1 represents aperspective view of my improved book-cover when opened and containing awriting book and copy, as will be hereinafter more fully described. Fig.2 is a detached side or edge view, upon an enlarged scale, of the devicewhich I employ for holding said writing book and copy in the cover. Fig.3 is a plan thereof with its pivoted arm swung to one side and thecopy-holder partly broken off for convenience in illustration. Figs. 4and 5 are sections through the back of the book-cover and ends of saiddevice for holding the writing book and copy, taken at the pointsindicated bylines a and'b, respectively, in Fig. 1. Fig. 6 is atransverse section through the back strip of said holding device, takenon line 0, Fig. 3, upon a still larger scale than said figure, lookingin the direction indicated by the arrow. Figs. 7 and S are a plan andedge view,respectively, of

the central part of the device, showing a modification in theconstruction, which will behereinafter described; and Fig. 9showsanother modification in the construction, also hereinafter described.

My invention relates to improvements upon the writing-book coverpatented in the United States by J. M. Kent September 6, 1887, numbered369,532, and which was assigned to me September 3, 1897, and recorded inthe United States Patent Office.

My said improvements relate to the means for holding the writing bookand copy in the cover, as will be hereinafter more fully set forth.

To enable others to better understand the nature and purpose thereof, Iwill now proceed to describe the same more in detail with reference tothe accompanying drawings.

In said drawings, A represents the bookcover, which may be of anydesired construction. In this instance itis provided with a pocket A inone end for the reception of writing materials, due. B represents awriting-book placed in said cover, and C my improved device for holdingsaid writing-book and the writing-copy D in the cover. Said holdingdevice 0 consists of the flat back strip d, having the ends at d curvedover, preferably eye-shaped, and the end (1 provided with a pointed end01 for the purpose hereinafter described. Said fiat back strip disfastened with its back against the inside of the back of the book-cover,with the ends at d flush with the edges of said book-cover, as is shownin Fig. 1. To said back strip dis pivoted at 6 under the curved end done end of a swinging arm f, which may be of any desired shape incross-section. It is preferably a thin fiat strip, similar to the stripd, only narrower, as is shown in the drawings. In the free end thereofis formed a transverse hole f, through which the pointed end 61 of stripd may be inserted to hold said swinging arm in the position shown inFig. 1, with the writing-book B under the same. Upon the swinging arm fis in turn mounted the adjustable swinging arm 9 for supporting thewriting-copy D at different points in the width of either side of thewriting-book B. Said swinging arm g is pivoted at its inner end to aslide-bearing g, fitted to slide longitudinally 011 the arm f. It may bearranged to slide thereon by fitting around the body of the arm, as isshown in Figs. 1, 2, and 3, or it may be arranged to slide in alongitudinal slot f in the arm, as is shown in Figs. 7 and 8, or in anyother suitable and convenient manner. In this instance the inner end ofthe arm g is pivoted to bearing g by forming a square bend at said innerend of said armwhich fits in a socket formed on said bearing, as isshown in the drawings, and is thus permitted to swing to either side, soas to bring the writing-copy (suspended thereon, as is shown in Fig. 1)to either side of the writing-book, as previously stated.

The object of curving the ends d 01 as previously described, and shownin the drawings, is to form supports or bearings at each side of thecenter flexible portion of the bookcover, so that the leaves of saidbook-cover may always be closed evenly-that is, with all its outer edgeseven with each other. lVhen no support of this nature is employed, as inthe patented device hereinbefore referred to, the back of the coverbeing flexible causes the leaves of said cover to wabble about inclosing the cover, and said leaves or sides are folded togetherunevenly, and consequently the edges are uneven, projecting outside atthe ends or sides beyond those of the other and presenting an unsightlyappearance. By the use of the curved ends on the strip (1 the innersides or leaves of the book-cover come against the sides of said curvedends (1 61 and by thus forming a support between the leaves of the coverwhen closed serve to guide and hold said leaves, so that they will foldas evenly as the leaves of the covers of any ordinary printed book. Thisfeature I find in practice is of great advantage over the patenteddevice previously referred to. In view of said device, however, I limitmy invention to the specific construction herein described, and pointedout in the claims.

If desired, .the arm f may be pivoted, as shown at e in Fig. 9, so thatit may be swung up instead of to one side without departing from theprinciple of my invention.

By the use of my improved device any bookcover or portfolio of theproper size may be readily converted into a writing-book cover, saiddevice being easily attached to the inside of the flexible back, aspreviously stated, and shown in the drawings.

The operation of applying a writing-book is also very simple, it beingonly necessary to press 011 the free end of arm f to detach it from thepointed end (I and then swing it over, place the Writing-bookinposition,swin g the arm back again, and refasten it under the hooked endd The swinging arm g may also be easily adjusted up or down and swungaround to bring the writing-copy at any desired elevation on thewriting-book, at either side of the same. As a pivoted arm carryinganother adjustable pivoted arm is already covered in the patent to J. M.Kent, previously cited, I make no claim, broadly, to said features, butlimit my invention, as above stated, to my specific construction.

What I claim as new, and desire to secure by Letters Patent, is-

1. The book-cover A, in combination with the writing-book andcopy-holder device 0, the latter consisting of the back strip clattached to the flexible back between the leaves of said book-cover, andhaving the curved and preferably eye-shaped ends (1 (Z with the end (Iterminating in a pointed or hook end d the swinging arm f, pivoted at eto one end of said back strip d, and adapted, at its opposite end, to beattached to the hooked end (Z the slide g fitted on arm f and the arm 9pivoted at one end to said slide 9, substantially as and for the purposeset forth.

2. In awriting-book cover, the combination of the book-cover with theback strip having the eye-shaped loops formed on the ends thereof, saidloops being bent upward, i11- ward and downward to form supports for theleaves of the book-cover when closed; means for fastening the back stripto said bookcover, and the swinging arm pivoted at one end to one end ofthe back strip andadapted to be .detaohably fastened at the other end,substantially as and for thepurpose set forth.
